JAMES LAMB, OF RICHMOND, INDIANA.

RAILWAY CONSTRUCTION.

Specification of Letters Patent.

Patented June 13, 1916..

Application filed August 30, 1915. Serial No. 47,939.

To all whom 'it may concern.'

Be it known that I, JAMES LAMB, a citizen of the United States, residing in the city of Richmond, in the county of I/Vayne and State of Indiana, have invented certain new and useful Improvements in Railway Construction, of which the following is an accurate and comprehensive description and exposition, the same being such as will enable others to manufacture and employ the same with precision.

The broad idea of my present invention is to secure protection on the construction herein set forth.I which involves certain new and novel features over that set forth in a former patient issued to me November 10, 1914i, which is numbered 1,116,446.

The object of my present invention, broadly stated, is to provide a rail road bed, including` the cross ties, and means for connecting the rails in position, which will be strong and durable in. construction; will be perfectly safe for traffic passing thereover; which can be manufactured and installed at a, coi'rnoaratively low price; and which will be practically indestructible.

Other objects and the specific advantages of my invention will be brought out in the course of the following description, and that which is new will be set forth in the appended claims.

One manner for carrying out the principles of my invention in a practical manner is shown in the accompanying drawings, in which- Figure 1 is a plan view of a portion of a railway as constructed in accordance with my invention. Fig. 2 is a cross section of a railway constructed in accordance with my invention. Fig. 3 is an enlarged detail cross section taken through one of the rails. Fig. 4 is an enlarged perspective view of one of the locking washers. Fig. 5 is a perspective view of a supporting plate. Fig. 6 is a cross section of the supporting plate shown in Fig. 5, as in operative position in connection with a railway rail and tie. And Fig. 7 is a side elevation of the arrangement shown in Fig. 6.

Similar indices denote like parts throughout the several views.

In order that the construction, the operation, and the advanta es of my invention may be made clear I wi l now take up a detailed description thereof, in which I will set forth the invention as fully and as comprehensively as I may.

Referring now to the drawings in detail: Numerals 1 and 2 denote two lines of parallel rails which form ya railway. The rails above mentioned rest on the cross ties, as the metal ties 3, Ll and 5, which I' prefer to form of steel or its equivalent.

In preparing the roadbed I first excavate two parallel trenches, whose centers are the same distance apart as are the centers of the said rails. These trenches are then filled with concrete, which is allowed to solidify, forming two parallel foundations 6 and 7, whose surfaces are true and level, that is conforming with the grade of the railway being constructed.

Numerals S and 9 denote the two lines of The ties 3, 4; and 5 restacross on the vmetal stringere which rest Hat on the surfaces of the respective foundations 6 and 7.'

stringere, to which they are connected at Y each end portion of each tie by a pair of with an aperture ktherethrough through which one of saidl bolts is disposed, and it then extends inward to the rail fitting over the base of the rail and extending up in contact with the web thereof, as shown in Fig. 3. A locking washer is then placed around the lprotruding threaded end of each of said bolts and resting on the surface of its respective clip, as shown by the respective locking washers m, n, 0, p, g, 1', s, t, u, o, w and a. The respective nuts 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32 and 33 are then run on the threaded ends of the saidl respective bolts, and they should be run down tightly against their respective washers, where they will be locked from inadvertent removal.

Numeral 34 denotes a substantially square Y ties.

plate which ishollowed out on its under surface forming a cavity for the concret-e 35, the edges of said plate resting on the foundation 7, for instance. One of the said ties rests across the center of each of the plates,`

there being apertures formed through the plate and through the ties to receive bolts, as the bolts 37 and 38 shown in Figs. 6 and7, the heads of the Vbolts beingon the underside of the plate, as shown, with the threaded ends of the Vbolts projecting up above the VExtending up from the sides of the plate,

toa height above the plate slightly less than the thicknessrof the tie are the flanges 89 and 40v with which the end portions of theY stringere are adapted to engage, as the stringer 41 shown in Fig. 5.; The said stringers may extend entirely across theV plate, or their ends may be bent down and hooked over the flanges 39 and 40 as shown. Thek rails l and 2, are adapted to rest on the stringers and extend parallel therewith and at rightangles toV the ties.

Iising from the plate 34 are the four braces 43, 44, 45 Vand-46 which are integral therewith. The saidbraces are connected at v one of their ends with the flanges 39 andr40,

and they extend parallel with theV rail to the sides of the tie, the upper ends ofthe said braces being adapted to Contact with the base of the rail. Located over the tie are the clips 47 and 48, whose bases rest on the tie, from' which they extend inward to 'and overthe base of therail and contact with the web of the rail to hold'the rail-in proper position. An aperture is formed through thek base of each clip 47 and 48V through which'project the bolts 37 and 38., .Lockingk washers- 49 and 50 are placed around the'bolts 37 and 38 and they rest on the surface of the base o fl their respective clips 47 and 48. The Vnuts l'and 52 are then:

run on the upper portion of the bolts 37 and 38 and they are run down tight against the washers 49 and 50, whereby the several parts will be locked together in operative position.

In practice the construction shown in Figs. l, 2 and 3; and that shown in Figs. 5, 6

,and 7, may be made and employed sepa? rately, however I have found that they may Vbe combined with greater advantage, thereby attaining a more secure railway construction, in Vwhich the construction shown in Figs. 5, 6 and 7 is placed at the abutting ends of two rails, and the construction shown in Figs. 1', 2 and Sis placed therebetween.

After the various parts are assembled asVV Y set forth the spaces between the ties, and between the rails, may be filled in with the (logics of lthis patent may beA obtained for parallel lines of rails forming a track, a

concrete foundation for each line of rails, a metal plate located below the abuttingends of the rails, each of saidplatesbeing substantiallyV square and hollowed out to form a cavity 'in its kunder side, the said plate be- Y ing adapted to rest on said foundation with theV foundation extending up into said cavity of the plate, a metal Vtie adapted to support 'the rails and resting across said plate, braces Vformed integral with the plate and extend- 'ingv up therefrom and adapted to prevent both the tie and the rail from slipping laterally, means for securing the tie to said plate, and means for securing the rails to the tie,

all substantially as set forth.

2. In combination with the two lines of i railway rails, cross ties onwhich the rails rest, and a concrete foundation for the cross ties, a metal plate resting on the foundationV and supporting the ties, the four spaced apart ybraces extending up from the surface of the plate and adapted to prevent lthe tiesk from movingfsidewise parallel with the rails and also preventing the rail Vfrom slipping sidewise parallel with the ties, bolts projecting upward through the plate and the ties to hold the tiesfrom slipping Vendwise,

venting the rails from slipping sidewise, all

vsubstantially as set forth.

3. The herein'described railway construction, comprising incombination with two lines of rails formingV atrack, a foundation 'foreach line of rails, a metal-plate located below the abutting ends of the rails, a metal tie disposed on each plate for supporting the ends of the rails, stringers connecting the metal plates and located above and parallel with the respective foundations, and means for securing Vthe metalp'late, the tie, and the rail in operativeposition, all. substantially as shown and described.

In testimony whereof I have hereunto subscribed my name to this specification inthe presence of two subscribing witnesses.
